软件无线电的直接射频采样ADC系统研究

Direct RF Sampling ADC System on Software Radio

提出了一种高速混合滤波器组 ADC系统 ,该 ADC系统能对射频模拟信号 (2 MHz～ 2 0 0 0 MHz)直接进行模 /数转换 ,而且分辨率达到 1 2比特以上。显然 ,用此高速混合滤波器组

A high speed hybrid filter bank ADCs is proposed,which can convert RF analog signal (2MHz～2000MHz) into digital signal with 12 bit resolution directly.It is apparent that the high speed hybrid filter bank ADCs can be used for direct RF sampling on software radio.
